STRAIGHTENING PRESS.

yApplication filed. May 1, 1920. Serial No. 378,145.

To all 'wlw/m, t may concern:

Befit known that I, FRANK S. JONES, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Straighteningv Presses, of vwhich the following)is a specication.

rior to my present invention it was usually the custom in straightening axles, shafts or other elongated articles, to place the article to be straightened inv thepress and, after operating the press, to remove'the article to a lathe or other centering means whereby the article could be supported and rotated in order to test the result of the pressing. Certain machines have been invented, however, where provision was made on the press for supporting the article after having beenengaged by the pressure screw inorder to -test the result of the straighteningbut in these latter mentioned machines the supporting means for testing the trueness of the article were in such position that unless they. were entirely removed from the machine they wouldinterfere with the prop er manipulation of the article during the pressing action.

@ne object of my invention is to provide a. straightening press which will include means readily adapted for testing the result of the pressing action without'requiring that thek article be removed from the press or its generalY position relatively to the pressure screw and at the same time to so construct the supporting or testing means that itcan be quickly and easily moved into such position as not to interfere with the proper manipulation of the article to the straightened during the pressing action. f

A further object is to make myinvention of adurable and comparatively simple construction.

These objects,y and other advantageous ends which'will'be described hereinafter, I

attain in the following manner, reference being had to the accompanying drawings in which Y Figure '1 kis a side elevation of 'myr improved straightening press.

Figure 2 is a fragmentary section showingA Occupied during the pressing operation 'of an article which is to be straightened.-

Referring lto the drawings, 6 represents a heavy vmetallic base which is mounted` on wheels 7` so that it may be easily rolled around on a floor and thisbase has a4 groove 8 providing a guideway for'V-blocks'Q in which the article, such for` example as the axle 10 which is to be straightened,`is posi'- tioned. rlyhe base 6 has'four studs 11" se:-

cured thereto which project`V above the top thereof; said studs serving to support' a head'12 having a pressure screw 13 therein adapted when turned to engage the article 10v between the blocks 9 for straightening purpses. A shaft 14 hasa Abearingnin'the base and projects beyondthe oppositejends thereof. Thisy shaft has a keyway 15'AL out longitudinally therein into which? project keys 16 in centering arms'l? said keys'l having end portions embracing opposite faces of said centeringv armsto retain the keysto the arms. The shaft 14C extends throughthe arms 17 and forms a lsupport for saidfarms as clearly shown in'Figure 1.; the arms being located adjacent opposite. ends of the shaft 142. Set screws 18 extendthrough each of thearms- 17r and areoperative to jamI the keys 16 into locking engagement with the shaft 111; said set screws being provided with vhand wheels 19 to facilitate their action.

engaging the ends of the article 10 after the latter has been pressed; it being necessary to slightly lift the article 10 out of the blocks 9 into alignment with the centers 2O as shown in Figure 1 so that by turning up on the screw threaded portions 21, the ends of the centers will engage the opposite ends of the article l0 and permit the latter to be rotated in order to test the trueness o-f the straightening action.

The shaft 14 is freely roclrable in the base 6 and said shaft 14 has a collar 23 secured thereto adjacent one end of the base 6; said collar having lugs 24 and 25 projecting therefrom as clearly shown in Figures 4 and 5. The base 6 has a stop pin 26 projecting therefrom and located between the lugs 24 and 25. A latch 27 is pivoted at 2S to the base 6 and has a detent portion 29 and a handle 30y projecting therefrom. When an article, such for example as the article 10, is in position upon the blocks 9 during the straightening action. The centering arms 17 are in the position shown in dot-and-dash lines in Figure 5 and are held in this position due to the engagement of the lug 24 with the stop pin 26. In this manner the centering arms are in a position entirely below the article 10 so that the latter may be moved lengthwise without interference. After the straightening action has taken place the arms 17 can be swung into an upright position as shown in Figures 1, 3 and 4, and the centers, after the article 10 has been raised from engagement with the blocks 9, can be moved into supporting engagement with the ends of the article 10 to permit theA latter to be rotated to test the result of the straightening action; it being noted that since the centering arms are secured to the shaft 14 that the entire shaft 14 will rock or partially rotate in the base 6 and the detent portion 29 of the latch 27 can be swung into engagement with the lug 25 so as to confine the latter between said detent portion and the stop pin 26. Thus the centering arms 17 and centers can be swung into operative position to support the article which has been pressed, without entirely removing said article from the machine and thus the straightening of the articlev is facilitated and the operation can be done conveniently.

lVhile I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to malte such vchanges and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A straightening press including a base,

straightening means, aligned blocks for supporting an article to be straightened, a shaft rockably mounted upon the base under, and in the same vertical plane with, the centers of the supporting blocks, arms slidably mounted upon the rock shaft and adapted to be moved to extend vertically above said shaft, means for locking the arms in their vertical position and centering members carried by the arms and movable into position to support the article above the supporting blocks, substantially as described.

2. A straightening press including a base havingvportions forming a seat for an article to be straightened; a shaft rockably mounted in said base and having portions projecting beyond the opposite ends thereof; centering arms secured to said shaft; centers on said arms located at positions remote from said shaft and adapted to be moved into a vertical plane above said seat; straightening means; and means for locking said shaft to the base whereby an article which is to be straightened can be supported by said centers in said position above said seat; substantially as described.

3. A straightening press including supporting means for an article to be straightened; pressing means for engagement with said article while on said supporting means; supporting arms having centering portions movable into position to support said article between said supporting means and said straightening means; means for limiting the movement of said arms when said position is reached; and means for locking said arms in said position; substantially as described.

4. A straightening press including a base; a shaft roclrably mounted in said base and having portions projecting beyond the opposite ends thereof; centering arms secured to said shaft; centers on said arms located at positions remote from said shaft; straightening means; a latch for locking said shaft to the base whereby an article to be tested can be supported by said centers, said latch being releasable to permit said shaft to be rotated to swing said arms and centers into a position out of alignment with said article; and means for limiting the movement of said shaft during said latter mentioned rotation; substantially as described.

5. A straightening press including a base; a shaft rockably mounted in said base and having portions projecting beyond the opposite ends thereof; centering arms secured to said shaft; centers on said arms located at positions remote from said shaft; straightening means; lugs secured relative to said shaft and spaced apart; a stop on said base projecting between said lugs; and a latch movably secured to said base and movable into a position to lock one of said lugs between it and the stop whereby the centering .for an article to be tested, said shaft being arms and centers will be locked in a position In testimony whereof I have signed my so that the latter can be used as a support tvvo subscribing Witnesses. rotatable to swing sald arms into a pos1t1on in which their centers are out of alignment FRANK JONES' with said article, said other stop serving to Witnesses: limit said latter movement by engaging said PAUL D.
